In some APPs, tapping or dragging in certain areas of the screen can not produce a response because the app's hot zones (the touch-sensitive areas) are too small or poorly mapped.
To solve the problem on your phone, please refer to the following methods:
1. Try restarting the phone to help resolve temporary glitches that can be affecting touch responsiveness. It resets any background processes that might be interfering with the app;
2. For apps that are still unresponsive, try clearing the app's cache or data;
3. It is recommended to update the APP version or report the issue to the APP developer for a solution.
